Discussion

This review explores composting methods for pollutant mitigation and nutrient recovery from sewage sludge, highlighting biological processes.

Biological composting methods enhance nutrient recovery and reduce pollutants like heavy metals and pathogens, improving agricultural suitability.
Among various strategies, vermicomposting shows significant potential for metal bioaccumulation and nutrient enrichment, benefiting soil health.
Challenges such as slower degradation rates and variability in removal efficiency highlight the need for optimized composting techniques.
Future research should focus on improving microbial consortia and bulking agents to enhance the breakdown of persistent pollutants like microplastics.
